15:24 So the people murmured 7 against Moses, saying, “What can 8 we drink?” 15:25 He cried out to the Lord, and the Lord showed him 9 a tree. 10 When Moses 11 threw it into the water, the water became safe to drink. There the Lord 12 made for them 13 a binding ordinance, 14 and there he tested 15 them. 15:26 He said, “If you will diligently obey 16 the Lord your God, and do what is right 17 in his sight, and pay attention 18 to his commandments, and keep all his statutes, then all 19 the diseases 20 that I brought on the Egyptians I will not bring on you, for I, the Lord, am your healer.” 21
